Fitness Function Evaluation Through Fractional Algorithms [PDF]
, 2011 This paper proposes a Genetic Algorithm (GA) for the design of combinational logic circuits. The fitness function evaluation is calculated using Fractional Calculus. This approach extends the classical fitness function by including a fractional-order dynamical evaluation. The experiments reveal superior results when comparing with the classical method.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Early functional improvement after stroke correlates with cardiovascular fitness
Kaohsiung Journal of Medical Sciences, 2018 Cardiovascular fitness exerts directly beneficial effects on functional and cognitive outcomes in patients of chronic stroke. However, the effect of early rehabilitation on cardiovascular function has not yet been thoroughly examined.

The bargaining model of depression [PDF]
, 2002 Minor depression—low mood often accompanied by a loss of motivation—is almost certainly an adaptation to circumstances that, in ancestral environments, imposed a fitness cost. It is, in other words, the psychic equivalent of physical pain.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

The role of histone modifications in transcription regulation upon DNA damage
FEBS Letters, EarlyView.This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Assessment of the efficiency of cognitive function of people over 65
Journal of Education, Health and Sport, 2018 Demographic estimates for Poland indicate that the average life expectancy of the population will increase further over the next decades. Weakness of memory is a physiological phenomenon affecting about 60% of people over 65, whereas the prevalence of ...

Le processus incapacitant au cours du vieillissement : rôle de l’exercice/activité physique
Bulletins et Mémoires de la Société d’Anthropologie de Paris, 2007 Aging is a phenomenon of increased importance in contemporaneous societies. Although it is well established that physical exercise/activity contributes to maintain functional fitness at optimal levels, physical inactivity is a largely prevalent behaviour
